Issues when upgrading from previous releases

Preupgrade doesn't work with default-sized /boot partition

Preupgrade is intended to provide a hassle-free method for upgrading a system to the current release of Fedora. Testing identified that users of Fedora 12 (and earlier) who installed their systems using the recommended /boot partition size of 200 MiB will not be able to upgrade their systems using preupgrade. The /boot filesystem is used to store the kernel and initial ramdisk images that form the core of the Fedora operating system. Its presence is required by several utilities including grub, kernel and preupgrade.

Users that have /boot partition size of at least 250 MiB should not have problems with using preupgrade. For others it is recommended to simply download Fedora 13 DVD/CD/netinst install medium and do a standard system upgrade. More experienced users that still want to use preupgrade may refer to these additional tips to free up space in /boot.

For Fedora 13 the default /boot partition size was increased to 500 MiB to avoid these problems in the future.

Text-mode upgrade fails when installing new bootloader

Users upgrading to Fedora 13 using the text-mode installer are advised to not select Create a new bootloader configuration. Creating a new bootloader configuration is not an intended function for the text-mode installer. Instead, users are advised to choose the upgrade or skip bootloader configuration options during a text-mode upgrade.

Installation issues

Space, Enter, and arrow keys don't work in x86_64 VNC installs

Due to a bug in tigervnc, some keys may not be work as expected when installing Fedora 13 64-bit using vnc. While some keys may not work as expected, users are still able to complete the install as directed using the mouse and keyboard. While this issue is resolved in future versions of Fedora, users may work around this problem by using an updates.img when installing Fedora 13 64-bit using vnc. For assistance on using an updates.img, refer to Anaconda/Updates.

Traceback when going back to modify Installation Repo

After customizing the install package set using the Customize Now option, users may encounter a failure when returning to the previous step and attempting to modify the Installation Repo. An updates.img is available that works around the reported problem. For assistance on using an updates.img, refer to Anaconda/Updates.

AttributeError: 'Ext4FS' object has no attribute 'mapName'

While testing Fedora 13, some users encountered problems while partitioning their disks. The cause of the failure is not yet known. The exact failure message changes depending on the partition selections. For example, the following failure messages were observed:

AttributeError: 'Ext3FS' object has no attribute 'mapName'

AttributeError: 'Ext4FS' object has no attribute 'mapName'

AttributeError: 'BTRFS' object has no attribute 'mapName'

Users experiencing this problem while installing Fedora 13, are advised to reboot the installer and retry. The reported problem does not occur on subsequent installs.

SystemError: (22, 'Invalid argument')

When installing Fedora 13 from a remote NFS share, you may encounter an exception referring to SystemError: (22, 'Invalid argument'). Investigation into the problem indicates the failure will occur when the Fedora installation boot media does not match the remote installation media available via NFS share. Users are directed to confirm that Fedora release used to boot the installer matches the Fedora available on remote NFS share. Users can confirm the boot media and remote installation media match by ensuring the contents of the .buildstamp match. The .buildstamp is available inside the images/install.img file. See the example below for guidance on inspecting the .buildstamp file.

Booting from an mdraid mirror without a separate /boot fails

Installing a new system with / on an mdraid mirror without a separate /boot will fail as anaconda creates the / mdraid set with 1.1 metadata which makes it unsuitable to boot from. Workaround: use a separate mdraid mirror for /boot if you want to boot from an mdraid mirror. This issue will be fixed in Fedora 14.

ValueError: Cannot remove non-leaf device

While modifying an existing software RAID1 disk configuration, users may encounter a failure while attempting to re-use the existing software configuration for another software RAID installation. Installing a new software RAID configuration will not result in failures. Specifically to Bugzilla #569469, a failure occurs while attempting to create a new software RAID5 device using the existing RAID1 disk members where there are insufficient RAID members to needed for the desired RAID installation. Users can work around this problem by creating a software RAID setup from scratch, or by creating a sufficient number RAID members before reusing an existing RAID device.

iSCSI install will not boot

Users may encounter a boot failure after installing Fedora 13 to a remote iSCSI volume. The problem is caused by the iscsistart command failing while attempting to find the root device on boot. An updated iscsi-initiator-utils-6.2.0.872-4.fc13 package that resolves the reported problem is available. Users installing Fedora 13 to a remote iSCSI volume are advised to enable the Fedora 13 Updates package repository during installation to ensure that the latest iscsi-initiator-utils package is installed.

Hardware-related issues

Miscellaneous graphical problems

If you are suffering from problems such as failure of X to start at all (including installer failure when switching to graphical mode), hangs or freezes or crashes in the graphical environment, display corruption, failure of 3D accelerated applications to work properly or similar problems, and your issue is not specifically covered elsewhere on this page, the following general advice may be of use.

First, make sure you have applied all system updates, in case the problem has already been fixed.

For AMD/ATI graphics adapters, several such issues may be worked around by disabling kernel mode setting. To do this, add

nomodeset

as a kernel parameter. If this solves your problem, please check whether a bug has already been reported for it, and if not, file a new bug report on the xorg-x11-drv-ati component, explaining your symptoms, and providing all the usual information required for X.org bug reports. In future kernel mode setting will be the only available method, and so we wish to ensure all problems caused by kernel mode setting are fixed. Please note that for Fedora 13, this workaround is no longer available for NVIDIA or Intel graphics adapters; using the nomodeset kernel parameter will result either in a non-functional display, or in the fallback vesa driver being used.

For further instructions on attempting to debug graphics issues, please refer to How_to_debug_Xorg_problems. That page also explains how to file good bug reports, if you cannot resolve the issue. In such cases, you can use the fallback vesa driver to get a graphical desktop working, though performance will be slow, 3D acceleration will not be available, it may not be possible to use the native resolution of your display, and more complex graphical operations such as video playback may be problematic. To enable the vesa driver on an installed system, follow the instructions at How_to_create_xorg.conf to create a /etc/X11/xorg.conf file, then edit this file and set the Driver line in the Device section to read:

Driver "vesa"

You may also need to set the nomodeset kernel parameter to prevent the native kernel driver for your graphics card interfering with the operation of the vesa driver.

To use the vesa driver during installation, at the initial screen that appears on booting the installer, select the option labelled "Install system with basic video driver". This will use the vesa driver for installation and will also configure the installed system to use the vesa driver.

To use the vesa driver during installation from a Fedora live image, press any key at the initial bootloader screen to allow configuration of the kernel parameters, and add the parameters xdriver=vesa nomodeset.

To use the vesa driver during upgrade from a previous version of Fedora using preupgrade:

Boot into the old system (rebooting from a failed or hung preupgrade attempt should do so automatically)

Login and open a terminal and run su -c 'preupgrade-cli "Fedora 13 (Goddard)"', and enter the root password when prompted

Edit /etc/grub.conf

Look for the first entry in the grub configuration, it should state that it is the preupgrade entry

Find the kernel line and append the options xdriver=vesa nomodeset

Save the file, and reboot

Boot pauses for a long time, with tpm_tis 00:0a: tpm_transmit: tpm_send: error -62 error displayed on console

Users of several systems, including Acer Travelmate 6465, 6592 and 6492 models, Zepto 6625WD and 6024W models, and Sony Vaio SZ7 series models (including, but likely not limited to, SZ71VN/X, SZ75MZ, SZ750N), have reported that their systems pause for several minutes during boot. If the boot process is set up so the console is visible at that point, the error message tpm_tis 00:0a: tpm_transmit: tpm_send: error -62 is shown on the console. Boot does eventually proceed, and the system works without side effects. There is no solution for this problem at present, but a workaround is available. Adding tpm_tis.interrupts=0 as a kernel parameter should avoid the problem in most cases.

Software issues

PackageKit silently fails to update

After installing Fedora 13 Alpha, some testers experienced a problem where the Software Update utility (provided by gnome-packagekit) fails to update the system software when requested. The Software Update utility will quickly report that the software update has completed without actually downloading and installing any updates. Running the Software Update utility again will show that no updates have been applied.

It is believed that a yum plugin provided by yum-langpacks may introduce package dependency conflicts, which will cause the update to silently fail. The problem may affect upgrades using both the Software Update utility and yum. Testing also demonstrated that the problem was difficult to reproduce and depends on whether the yum-langpacks plugin is installed, and whether certain conditions exist in the package repositories used during the update.

If you are unable to update your system and the problem description above matches your symptoms, you may work around the issue by removing the yum-langpacks package. To remove the package you may either:

Open a terminal and type: su -c 'yum remove yum-langpacks'

Or, from the default Desktop environment

Select the System -> Administration -> Add/Remove Software menu item

Enter the text yum-langpacks in the text-box

Deselect the check-box associated with yum-langpacks and select, Apply

GNOME Shell fails to run at all

Fedora 13 Beta includes version 1.2 of the Clutter toolkit, but gnome-shell has not yet been ported to work with this version. As a consequence, in Fedora 13 Beta, any attempt to use GNOME Shell will fail. Work to port GNOME Shell to Clutter 1.2 is under way, and we hope to include a usable GNOME Shell in Fedora 13.

Picasa fails to login to google

Google bundles a version of wine with their picasa package (bad google). This version of wine is linked against a different libssl library and therefore won't work with https addresses which is needed to login to google services.
